Heat Transfer

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation 

The man goes to take the hot pot off the stove with his bare hands.

• conduction
• convection
• radiation

What happens when ice cubes melt in a glass?

• Heat travels from the ice to the warmer water.
• No energy is transferred.
• Heat is transferred from the warmer water to the ice cubes.
• The water warms up due to the humidity

• conduction
• convection
• radiation

Why does food wrapped in aluminum foil keep warm for a long time?

• Aluminum foil is an insulator and prevents heat loss by conduction.
• Aluminum foil forms an air-tight seal and prevents heat loss by convection.
• The silver surface of the foil reflects heat in and prevents heat loss by radiation.
• The silver surface of the foil absorbs heat from the surroundings and keeps the food warm.

• condensation
• conduction
• convection
• radiation
